Countdown + Bootstrap4 not working

[jesusvpct]

I've tested Countdown module combined with Bootrstrap4 module and it does not show the countdown. Tried on PNotify web page.

I ran into this and figured out it was missing the color styles. I had to add the background colors to match the bootstrap alert and the darker one for the bar. Such as for danger and info alerts:

[data-pnotify] .alert-danger .bootstrap4-countdown {
background-color: #f8d7da
}
[data-pnotify] .alert-danger .bootstrap4-countdown-bar {
background-color: #f5c6cb;
}
[data-pnotify] .alert-info .bootstrap4-countdown {
background-color: #d1ecf1
}
[data-pnotify] .alert-info .bootstrap4-countdown-bar {
background-color: #9fe9f5;
}

What I've not yet figured out is how to fix the pin/unpin icon which is not swapping icons with bootstrap4 enabled.
